Application filed August 23, 1917. Serial No. 187,399.

To aZZ whom it may concern:

e it known that I, PATRICK 'lnonms Gianni/Ens, a citizen of the United States, residing at Forest City, in the county of Susquehanna and State of Pennsylvania, have invented certain new and useful Improvements in Devices for Adjusting and Testing Motor-Vehicle Brakes; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates generally to motorvehicle accessories, and more particularly to a device for testing and adjusting the brakes of a motor vehicle.

The primary object of the invention is to provide a device by which the strength of the brakes of the wheels of the motor vehicle can he tested or measured so that the brakeon either driving wheel of the vehicle may be adjusted so that its braking eficiency equals that of the oppositewheel.

Another object of the invention is to provide a device for testing the brakes of motor vehicles which can be readily and easily attached to or removed from the wheels or the vehicle, and which is so constructed that it may be fitted to wheels of various sizes.

A further object of the invention is to provide a brake testing device for motor vehicles, including as one of its parts a comparatively long beam on which is slidably' mounted a weight, said beam being hingedly connected to the portion of the device which is clamped to the wheel of the vehicle; so that, when the device is not in use, the beam may be folded along one side of said portion of the device to form a comparatively small and compact article which can be carried at all times in the vehicles without inconvenience, or which can be packed away in a comparatively small space.

a l still further object of the invention is to provide a device of this class which will be simple, strong, durable and inexpensive in construction, efiicient and reliablein operation, and well adapted to the purpose for which it is designed. w

With these and numerous other objects in view, the invention consists of certain novel features of construction, and the combination and arrangement of parts as will be hereinafter fully described and claimed.

in the accompanying drawings, forming a part of the application, and in which simisaid weight in lar reference characters designate like parts throughout several views:

Figure 1 is a side elevation of an automobilewheel, having a device constructed in accordance with this invention applied thereto.

Fig. 2 is a horizontal sectional view of the automobile wheel, showing the brake testing device applied thereto in top plan view.

Fig. 3 is a perspective view of the brake testing device detached from the wheel and in open or extended position: and,

Fig. 4 is a similar view of the brake testing device in closed or folded position.

Referring more particularly to the drawings, the letter A, designates an automobile wheel, B the hub thereof, and C spokes. Clamped to the wheel in a manner to he hereinafter described is a bar 1, said bar being preferably made of a flat strip otiron or other suitable metal and having a laterally ofi'set portion 2, at its middle portion. The portion? is of greater length than the greatest width or diameter of the hub B of any automobile wheel. One end of the bar 1 is twisted to form an ear 3 lying in a plane at right angles to the major part oi the bar, and pivotally secured to the ear 3 is a hook which is upwardly concaved to engage the lower side of a spoke C. I

Hinged or pivoted to the other end of the bar 1 is a bar or beam 5 having graduations 6 thereon. The inner end of the beam 5 is,

ends of said bar to maintain said beam in this a position. Slidably mounted upon the beam 5 is a weight 7. A set-screw 8 extends through one side of the weight 7 and engages the adjacent side of the beam, to look its adjusted position upon said beam- The reference numeral 9 represents a hook which'is formed integrally with an arm 10 which extends from one end thereof and has its free end upturned as shown at 11, and

this element 11 has threaded engagement with a set-screw 12. The hook 9 and parts integrally connected with the same are not permanently connected with either the bar 1 or the beam 5, but are primarily separate from the same. The set-screw 12 extends toward one side of the hook 9, and this side Patented (lot. 22, 191%.

wheel, a downturned hook at the other end of said bar and removable toward and away from the same said down turned hook being adapted to hook over the diametrically opposite spoke of the vehicle wheel, a beam extending from one end of said bar, and a weight slidably mounted upon said beam.

7. A wheel brake adjusting device comprising a bar provided with means whereby it may be detachably connected to a vehicle a wheel, a. beam pivotally mounted at one end of said bar and provided with means whereby it may be secured in longitudinal ahnement with the same, and a weight slidably.

mounted upon said beam. v

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses. v
